Gingerbread House Kit Card - fixed stronger model

Based on: https://www.thingiverse.com/thing:4689896

And the broken stronger variant: https://www.thingiverse.com/thing:5161204

Stronger meaning, the card kit does not detach into pieces the moment you pull it of the print bed.

The stronger variant had model issues and defects stemming partially from issues from the original it seems. Including a stronger peg that was not properly modeled and printed detached out of the box.

This model fixes those issues and includes a hidden/indented "inner side" instruction for the chimney wall for people receiving this to properly build the house.

Has the snow and heart shapes redone to be pretty and complete.
